    Calibrating a Level Gauge to the 505ITM Overview All of the input modules on the 505ITM are calibrated at Qualitrol, except for the Potentiometer (Level Gauge) input modules. These modules and sensor inputs are specific to the transformer with which they are associated and must be calibrated on the transformer.
  • Page 99 Calibration Procedure Connect the computer to the 505ITM start the Remote Software. The Desktop Menu window displays. 2. Click [Connect] and enter the password (505) for the Calibrator tool. 3. Click [Start]. The Calibrator - Signal Selection window displays with the radio button for Input 1 selected.
  • Page 100 4. Click the radio button for the input module that displays “Potentiometer.” In the example above, this is Input 3. Check again that you have selected the correct input module before CAUTION: proceeding. Calibrating any other input module could erase the system’s calibration values and cause the 505ITM to malfunction.

  • Page 102 The Input Channel Calibration window displays. The Set input signal to field prompts you to set the pointer to minimum (“MIN”). 6. Adjust the case face until the pointer is set at the minimum position. Case face adjusted with the pointer (and potentiometer) moved to minimum 7.
  • Page 103 The Input Channel Calibration window now prompts you to set the pointer to maximum (“MAX”). 8. Adjust the case face until the pointer is set at the maximum position. Case face adjusted with the pointer (and potentiometer) moved to maximum www.qualitrolcorp.com...
  • Page 104 9. Click [Finish]. The Level Gauge is now calibrated to the 505ITM. The Minimum value will read 0% on the LCD display and the Maximum value will read 100%. 10. Immediately exit the Calibrator tool. 11. To use the Level Gauge for alarm setpoints: (a) Adjust the case face until the pointer is set to an alarm value, either low or high.

The Microsoft Windows version is available on the CD-ROM sent with the ITM or the very latest can be obtained from the Silicon Laboratories website: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx.
  • Page 106 Frequently Asked Questions About the 505ITM In the Simple CT Temperature Scaling Setup window, what is the “Oil Temperature Adder”? And where do I get the values for the other three variables? Simple Calculation Setup Method, which uses the Simple CT Temperature Scaling Setup window, calculates the winding temperature of the transformer by using the oil temperature of the transformer and the load or current running through the windings.
  • Page 107 What is the difference between failsafe and non-failsafe for a relay? In the 505ITM, Qualitrol uses Form C relays. These relays have three contacts: normally open, normally closed, and common. When the monitor has no power applied, the common and normally closed contacts are shorted together, while the common and normally open contacts are open.
  • Page 108 109.73 ohm 146.06 ohm Because of the small resistance values in an RTD sensor, Qualitrol recommends a maximum of 75 feet of cable length. A typical application to measure the resistance (temperature) changes in an RTD is for a monitor to send an excitation current through the RTD and then measure the voltage across the device.
  • Page 109  contact Qualitrol about updating the 505ITM unit in the field (purchasing a new module and getting an update software disk). 2. The calibration for the RTD Input Module has been altered or overwritten. If the 505ITM was incorrectly recalibrated in the field, reinstall the factory calibration settings.
